Tilted Forum Project Discussion Community - [obj-c] not key value coding-compliant for the key NSDevicePath or F#$King Docs!!

okay so in my application I have one of my classes register for the "NSWorkspaceDidUnmountNotification" notification. Fine. Working, when I eject a volume I get the notification and it calls my function. Cool up to here.

Here is the code in said function.
Note: NSDictionary is a hashtable (if you've never encountered the term)

PHP Code:


		
			
NSDictionary *instructions = [note object];

NSLog(@"mediaWasEjected - %@", [instructions valueForKey:@"NSDevicePath"]);

But when it executes I get this error message.

from apple docs, Notifications are at the bottom.

NSWorkspaceDidUnmountNotification
Posted when the Finder has unmounted a device.

The notification object is the shared NSWorkspace instance. The userInfo dictionary contains the following information:

Key_______________Value
@"NSDevicePath" ____The path where the device was previously mounted, as a string.

So I get the dictionary and ask it for the value with key @"NSDevicePath" but the dictionary says "Nope" and raises a exception. :hmm:

*sigh*
okay I feel better now.
